FLAME-TITEASURING DEVICE.

.Application filed August 18, 1922. l'Serial NO. 582,657.

To aZZ whom t may concer/rt: y

Be it known that I, JAMES B. RATHER, a Vcitizen of the United States of America, and a resident of the borough of Brooklyn, county of Kings, city and State of New York, have Vinvented certain new and useful Improvements in Flame-Measuring Devices, of which the following is a specification'.V

My invention relates to flame-measuring devices, and has for its object to provide a simple and novel device whereby the dimensions of the flames-of kerosene lamps, hoth as to breadth and height, may be measured in an efficient and reliable manner and with a minimum of effort.. Other objects of my invention -will appear from the description -hereinafter and the features of novelty will be pointed out in the appended claims;

lnthe accompanying drawings, which illustrate an example .of my invention without defining its limits, Figure l is a front elevation vof the flame-measuring device ;'v Fig. 2 is a side elevation thereof; Fig. 3 is a plan view, and F ig. 4 is a diagrammatic view .illustrating the type vof flame for which thedeviee is particularly adapted.

In its illustrated form, the device comi prises members 5 and 6 arranged in pairs and each provided with slots 7 extending lengthwise thereof, asvshown invFig. l; the members 5 and 6 of each pair are arranged in spaced relationjto and in registry with each other, as shown in Fig. 3, and are mounted upon carriages 8 adjustable length.- wise in the grooves 9 of a support 9a. rlhe latter Vis provided with fixed bearings i0, in which adjusting screws *10a are rotatably mounted in a manner to prevent lengthwise Vmovement Vrelatively to the bearings 10. The adjusting screws 10at are in screwj threaded engagement with lugs 82? forming part of or secured to the carriages 8, and are preferably provided with manipulating heads 10b. A member 11, upon which a scale llis produced, is fiXed upon one ofthe members of `one of the pairs and extends movably across theface of one of the other pairv of members; inthe illustrated example,the member ll vis carried by one of the members 5, preferably. at the upper end thereof, and extends movably across the `face of thev cti-operating member 6 of the other pair. The grcoved support 9n is hingedat l2 uponv a support 13 which, as shown, may

be in the. form of an upright stand mounted upon a base. 14 and having a horizontal member l5 upon which the grooved support 9a is arranged to rest when the parts are in l' positionillustrated in F ig. l. In the preferred arrangement the support 9a is provided with an auxiliary scale 9b vfor the purpose to be more fullyv set forth hereinafter. VTheV members 5 and 65 constitute measuring elements v*adjustable relatively to each other to measure distances asrwill appear more vfully from the description hereinafter.

.In practice, yassuming that it is desired to first measure the width of a flame, lthe parts of the` apparatus will occupy the positions shown in the drawings. ln such case,- alamp is placed in front of thedevice anda sight is tak-en through the slots 7 of the members 5 and the latter arel shifted or adjustedby means of the adjusting screw l0arand 'head l0b until said slots register with each other and with the one edge .ofthe flame' to be Vmeasured. Asight' is then vsimilarly taken ,through they slots of the members 6 and the Y latter are-adjusted by means of the adjusting screw 10iL andV :its lhead l0b until lsaid slots 7 align with each other and with the taken from the scale'lla, which indicates in soV l'other edge ofthe flame. A reading is then predetermined units of measurement the;V

width ofsaid flamegfit will be understood that the scale 1la begins at the right-hand edge ofthemember 5in Fig." l and that'the scale'is read in connection .with the right- 'hand'edge of the member 6 in said figure.

VTo now measure the heightv of the flame, the supportv 9aM isswung upon the hinge l2 Vto .an-upright position and into surfaceengagement with the upright member 13 vof the stand or support, so that the members 5L and 6 now project in horizontal directions.

A sight is then taken through the slots 7 of the members 5 and vthe latter are adjusted in the manner previously described until said -slots 7-register with 'each other and with the base of the flame. If the 'base of the flame is below the level of the flame spreader on thelamp burner used in the test and this burner is of thetype known as a hinged burner, the reading may be taken vbefore the lamp is ignited and the position of fthe members 5 with `reference to the top ofthe wick guide kor holder of the burnernoted on the auxiliary scale 9*. lThen at any time during the conduct of `the `test the slots 7 of the members may bebrought into alignment with the base of the llame by adjustingsaid members 5 to the previously as#V fof measurement the height of said llame.

The dimensions of a -tlame,both as Vto Y breadthvand height, are thus easily measured esv f 2. A measuring device by simply. swinging Vthe support .9a into horizontal and vertical.positions,'respective ly, and then adjusting the members and 6 to bring the Vslots .7 thereoil into registry with each other and with the predetermined pai-ts of the flame in the manner previously described. Y,

The instrument or device is intended'primarilyfor use in Vconnection with oil tests, and more particularly in tests for kero-k sene oil which is used, to a large extent, inV

household lamps, railway signal lamps and the like. Up to the present time the most satisfactory flame measurements have been procured with the aid'ot a measuring nevice known as a photometer, whereby the flame is compared with a standardized source of light, and which requires the use of complicated and expensive apparatus and equipment including, for instance, a darli i room-for conducting the test. rEhe present device overcomes the necessity for such com- Y plicated apparatus and equipment and makes it possibleto positively and accurately adjust Haines to predetermined dimensions and thereby `secures an absoluteY uniformity in l'the candle-power development. Y j kThe device is simple in construction` and is easily operated without the `necessity for any particular skill, and may be utilized in a variety odilierent ways'.

Various modifications may be made Within the scope of the claims withoutdeparting Vfrom the nature of my invention.
